RUN
STRAIGHT RUN
The figure at right shows a typical straight section of conveyor.
Note that the conveyor frame is designed to support the chain on
the bottom of the link. The wear strip
spacing is varied
to
distribute the wear evenly across the bottom of the link. This
open design is preferred over full width support since it prevents
the build-up of debris in the track. For dry abrasive conditions
use steel wear strips. For wet abrasive conditions use stainless
steel wear strips. For non-abrasive conditions use UHMWPE or
Nylatron
®
.
The chain is fully supported at all points in the conveyor. The
chain is guided by two side members as shown in Section A-A.
Chain guides are of such a height that they would not interfere
with a product that may overhang the sides of the chain.
Very wide products can be handled on this chain through proper
product guide rail spacing and design (guide rails not shown in
Section A-A).
CORNER SECTIONS
The corner discs guide the chain around the corner. Corner turn
discs are used to guide the chain without significant increase in
chain tension. For curves of 15° or less, it is possible to use a
conventional stationary curve (wear strip). (For 1701, 1702, 1701
TAB, and 2500 chains stationary (sliding) curves can be used for
any corner turn.)
The chain supporting members, chain guides, and product guide
rails for corners are similar to those used in the straight sections.
The corner sections of the conveyor provide full chain support.
The corner discs are positioned in such a manner that the chain,
while being engaged with the disc, is also being supported by the
wear strips.
The chain guides are provided on the outside of the curve while
the corner turn disc provides guidance on the inside of the curve.
It is very important to have the chain enter and leave the
disc in the same plane as the disc. This is necessary to
maintain the chain on the disc.
